Positron emission particle tracking (PEPT) is a noninvasive technique capable of imaging
the three-dimensional dynamics of a wide variety of powders, particles, grains, and/or fluids …

The positron emission particle tracking (PEPT) technique has been widely used in science
and engineering to obtain detailed information on the motion and flow fields of fluids or …

In this paper we study the effect of multiple spouts on the bed dynamics in a pseudo-2D
triple-spout fluidized bed, employing the discrete particle model (DPM) and non-intrusive …

In comminution circuits, grinding is the most energy-intensive process. Although significant
work was focused on the charge particle dynamics via only DEM in the past, but lifter effects …

In this study, microwave irradiation is used to modify ilmenite surface chemistry to enhance
the adsorption of surfactants and the air bubble attachment. The results indicate that …

The motion of grains in a three-dimensional vibrofluidized granular bed has been measured
using the technique of positron emission particle tracking, to provide three-dimensional …

The time-averaged solids velocity profiles in a freely bubbling, three dimensional, gas–solid
fluidized bed have been experimentally quantified for two different bed materials and …

Free, buoyancy-driven convection has been observed experimentally in three-dimensional
highly fluidized granular flows for the first time. Positron emission particle tracking was used …

Positron emission particle tracking (PEPT) is a non-invasive technique used for obtaining
dynamic information within multiphase systems. It involves tracking a single radioactively …

Circulating Fluidised Beds (CFB) are attracting increasing interest for both gas–solid and
gas-catalytic reactions, although the operating modes in these two cases are completely …
